` LUBRICATED ROLLER SIDE`BEARING.

Application led February 27, 1922. Serial No. 539,479.

T all whom t may concern:

Be it known that I EDWIN G. BUSSE, a citizen of the United tates, residing at the city or Chicago, county of Cook, and State or Illinois, have invented a certain new and useful Improvement in Lubricated Roller Side Bearings, or which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, rererence being had to the accompanying drawings, forming part of this application, in

` whichimproved roller side bearing.

Figure 2 is a top plan view of the same partially in section.

Figure 3 is an end elevational view, and

Figure 4 is a side elevational view partly in section illustrating a modied form.

This invention relates to anew and useful improvement in lubricated side roller bearings, the object being to construct a device of the character described, which is simple and eicient and one in which the lubricating charge may be renewed without dismantling the bearing.

Myl present invention is designed as an improvement upon the type of bearing shown in the patent to Ernest A. Le Beau, No. 1,106,824, dated August 11, 1914.

In the drawings, 1 indicates the base plate of a roller side bearing, in this instance, shown as the bottom bearing, i. e., one which is designed to be mounted upon the truck or truck bolster of a railway car. This bearing is provided with upwardly eX- tending walls 2 apertured to receive ashal't or roller pin 3.

4 is the roller bearing varranged on pin 8 and-between the walls 2. Pin 3 is prevented from longitudinal movement by means of cotter pin 5. One of the walls 2 is provided with a grease cup, or cups, 6 open at its upper end and through which opening ac cess may be gained to the interior of the cup, said open end being closed by a gravity lid 7 preferably held in position by means of a cotter pin 8.

Pin 3 is shown in Figure 2 as provided with a central bore 3a open at one end into grease cup 6, said central bore being provided with lateral ports 3b, which commu` nicate with the bearing surfaces of the pin, and with oil grooves 4a in the roller;

lubricating chamberin which is arranged a' spring follower 10 in the form of a piston.

11 is a cap threaded on thebossV 9, which cap when screwed inwardly, exerts pressure upon coiled spring 12 ybearing against the piston 10, whereby energy isleirerted upon said piston'to force lubricant into the roller pin ports, thus lubricating the roller as be,-v

iiore described.

While I `have mentioned the grease cap 6 as being preferably filled with waste, it is obvious that waste need not be employed. 'l

IVhatI claim is:

, 1. A lubricated roller bearing comprising a support, a ported roller pin mounted therein, a roller bearing on said pin and having a plurality ofgrooves in its bore registering with opnositely disposed ports in said fpin, and anf eXternally arranged lubricating chamber in direct communication'V with the portsy of said roller pin.

2. In a bearing, he combination of sup- ,ports, a ported rollerpin mounted in said supports, a side bearing roller rotatably. mounted on said pin, an externally arranged v lubricant chamber formed integral with said support at one end of, and in axial alinement with, said pin and in vcommunication with the ports of said roller pin, and

a closure for said chamber.

3. In a roller sider bearing, the combination of a support, a ported rollerpin in said support, a roller mounted on said pin, a lubricating chamber, the walls of which are integral with said support, a combined piston and spring seat follower in said lubricating chamber, an adjustable capfor closing said chamber, and a spring interposed between said cap and said piston-spring seat follower. v i

In testimony whereof I hereunto aiix my signature this v17th day ofy February,v1922.

EDWIN G. BUS'SE.
